exportKeyingMaterial

byte[] exportKeyingMaterial(java.lang.String asciiLabel,
                            byte[] context_value,
                            int length)

Export keying material according to RFC 5705: "Keying Material Exporters for TLS".

Parameters:

asciiLabel - indicates which application will use the exported keys.

context_value - allows the application using the exporter to mix its own data with the TLS PRF for the exporter output.

length - the number of bytes to generate

Returns:

a pseudorandom bit string of 'length' bytes generated from the master_secret.
